Differences in means=the mean difference of the pre-post estimates between the intervention and the control group, control-intervention group;

Adjusted for employment status and group allocation;

PSQI: Pittsburgh sleep quality index; Fatigue score is based on the PROMIS Fatigue short form 4; Daytime sleepiness is measured by the Epworth Sleepiness Scale (ESS); Sleep disturbance is measured by PROMIS Short Form v1.0-Sleep Disturbance 6a
